Voltage Monitoring Type SW

DC Limit Relay for Standard Signals

DC 0/4 - 20 mA, 0/2 - 10 V

STW1000V2

Part number:

S225677 AC/DC 24- 240 V

ZIEHL STW1000V2 current relays monitor standard signals from instrument transformers for compliance with a limit value.

Units can be wired in series

(current) or in parallel (voltage) to monitor multiple limits.

Measurement inputs for 0/4-20 mA and 0-10 V, adjustable hysteresis and switching delays plus the selection facility to choose between the normally closed current and normally opened current principle for the relay make it a universal limit switch.

Application:

Monitoring nearly any measured quantity in connection with instrument transformers, e.g., in plants and controls.
